This general area of discussion has interested me for nearly a quarter
of a century, if not more. I graduated with a degree in design
(concentrating in product design) in 1983, and shortly thereafter my
experience with the Macintosh set my career's goal - to be a pioneer in
human interaction in products, software, and systems, and to approach
this as designers in my own tradition had always done.

I am going to disagree on this. While I don't think a Master's degree
is the end-all be-all in the field, I think a good program can teach
some good fundamentals on which to base your later work on. That being
said, yes, I would probably take a seasoned IxD vet over someone just
out of school, but when I am looking at similar years of experience, the
Master's degree is going to weigh heavily in your favor (even if you
have slightly less experience.)

I am working as a Interaction Designer in India. I cannot go to US or
UK for getting an MS. I wanted to know if there are any universities
which give online or correspondence master's degree courses for IxD.
